Hi John,
I have an unlocked Torch 9800 that I got in Jakarta. I'm in california, near LA, and I got a T-Mobile monthly plan with BB service.
When I got the phone set up, the Browser didn't work. I called T-Mobile Technical Support and they were not able to help. So I followed your instructions for the BIS Connection and BIS Browser, downloaded the T-Mobile service books and installed that. The Browser worked after that.
The problem now is, Blackberry Messenger stopped working. I lost the saved chats and groups, and now I can't send messages to my contacts. Thankfully my Contacts were wiped out.
Can you please help me?
